Reliance Infra, which runs the Delhi Airport Metro line, has refused to operate it beyond June 30, a notice rejected by Delhi Metro Rail Corporation (DMRC) Friday which termed it as a "violation" of the Concession agreement and the ongoing arbitration proceedings.

Reliance Infrastructure (RInfra) Friday said its Delhi Airport Metro Express has launched a 30-trip monthly pass for commuters that will make travel cheaper and minimise the waste on account of unused trips.
